Unpaired Self-supervised Learning for Industrial Cyber-Manufacturing Spectrum Blind Deconvolution

Cyber-Manufacturing combines industrial big data with intelligent analysis to find and understand the intangible problems in decision-making, which requires a systematic method to deal with rich signal data. With the development of spectral detection and photoelectric imaging technology, spectral blind deconvolution has achieved remarkable results. However, spectral processing is limited by one-dimensional signal, and there is no available structural information with few training samples. Moreover, in the majority of practical applications, it is entirely feasible to gather unpaired spectrum dataset for training. This training method of unpaired learning is practical and valuable. Therefore, a two-stage deconvolution scheme combining self supervised learning and feature extraction is proposed in this paper, which generates two complementary paired sets through self supervised learning to extract the final deconvolution network. In addition, a new deconvolution network is designed for feature extraction. The spectrum is pre-trained through spectral feature extraction and noise estimation network to improve the training efficiency and meet the assumed noise characteristics. Experimental results show that this method is effective in dealing with different types of synthetic noise.
